This website is a comprehensive site providing all you need or want to know of Caye Caulker, Belize. Inside lies a library of information, from the rich history of the island to the activities and conservation efforts that entice many tourists visiting Belize to experience the island's wonders and fun.

On early British maps the island's name is spelled "Cay Corker." Known historically for its plentiful supply of exposed fresh water at La Aguada, one theory holds that this island was a favourite stop for sailors to replenish and cork water bottles. The Spanish name of the island is Cayo Hicaco, which means "the island of the cocoplum." "Caye Caulker" could be an anglicized pronunciation of Cayo Hicaco. Another theory is that boats were caulked in the protected bay, La Ensenada, on the western side of the island leading to the "Caulker" name.
